Hey there, @joemiami1971
Bo here from Shopify Support!
Thank you so much for reaching out regarding this, it is a really great question. So, from my understanding you would like to hide the Shop Pay button and only have Amazon as your accelerated checkout, would that be correct? If so, in order to do so you will simply need to turn off Shop Pay in your Shopify Payment Settings. I will go through the steps below and include some screenshots from my test store.
This will prevent Shop Pay, Apple Pay, and Google Pay from appearing as an accelerated checkout. Please note that if you only want Amazon to show up as an accelerated checkout you will need to disable PayPal entirely as there is no way to suppress PayPal yet have Amazon appear.
Let me know how this goes and if there is anything else I can assist you with, I'm happy to help!
All the Best,
